I\'m trying to add a jsp page in my Spring Boot service. My problem is that every time I try to go to that page I have this:

Whitelabel Error Page

We were adding Spring Boot to our system in order to run it as executable application without standalone tomcat and also faces the 404 status during JSP initialization.
What should be done for fixing it:

a) Add dependencies to your pom file (WARNING: tomcat-embed-jasper must have compile scope no provided):

 org.springframework.boot
     spring-boot-starter-parent
     2.3.3.RELEASE
     
 
 
   
     org.springframework.boot
     spring-boot-starter-web
   
   
     javax.servlet
     jstl
   
   
     org.apache.tomcat.embed
     tomcat-embed-jasper
   
 

b) Add spring boot maven plugin for building your application:

    
      
        org.springframework.boot
        spring-boot-maven-plugin
      
    

c) Check that you are using *.war file for your artifact, not jar (because of JSP support limitation):

war

e) Now you should be able to run your spring boot application using maven plugin or with command line - java -jar /you/path/application-name.war:

f) But if you are using multi-module maven project and want to run spring boot application using IntelliJ Idea it is important to change "Working directory" -> $MODULE_DIR$:
